After much speculation about the date of birth and the official baby name Beyonce Knowles and Jay-Z have released an official statement regarding their baby:

Hello Hello Baby Blue!

We are happy to announce the arrival of our beautiful daughter, Blue Ivy Carter, born on Saturday, January 7, 2012.

Her birth was emotional and extremely peaceful, we are in heaven.

She was delivered naturally at a healthy 7 lbs and it was the best experience of both of our lives.

We are thankful to everyone for all your prayers, well wishes, love and support.

- Beyoncé & JAY Z

So that means no C-Section as previously reported and that her name is Blue Ivy, and not Ivy Blue as previously stated.
